Since Polish brands use different sizing systems, we've converted everything to US sizes. On product pages, we always list the US band and cup size conversion first, followed by the brand's native size in parentheses.

IMPORTANT: Polish bras run tight in the band and sizing varies by brand. We strongly recommend sizing up a band size (+ sizing down one cup letter to maintain the same cup volume). Our fit notes provide guidance on how to adjust your size for the best fit in each style.
